I don't know what went wrong...I was happily colour burning different colours onto the new M5 (the BMW websites only has wallpapers with it in silver).

Then suddenly, for some odd reason, the burning started to overlap previous burns if I let go the mouse button! Before, it would only colour burn to a certain point then thats it...it didn't care if I let go the mouse button at all or overlapped previously burned places! I don't know what button I pressed to cause this...someone help!
